I agree with you. I am a 5x user; compared to 6 months ago, I rarely reach session or weekly limits. It got slightly slower, but fewer mistakes make up for it. Probably the commenter above is a heavy vibe coder launching a bunch of background agents to reread the base code over and over.

I'm on 5x also, and lately (this week), the window seems more generous, even on Fable. I wonder what's going on.
